FLAT-SUPPORTED MEASURING POT.

Application led December 30,1927. Serial No. 243,518.

tity made available at each time is automati cally rendered uniform Provision is, however, made for preleniinary adjustment of the relative position Of the parts so that the saine `apparatus may be adapted fora variety of operations in some of which a greater or lesser quantity of the babbitt perfladling operation is required.

Tn the drawings:

Figure l is a plan view of my improved apparatus shown in position relatively to a vat or melting pot. Y v

Figure 2 is an elevational view largely in section, taken along theline 2-2 of Figure l, and looking in the direction of the arrows there shown.

Figure 3 is a fragmentary elevational view, taken along the. lineS-S of Figure l, and looking in the direction of the arrows there shown.

A represents a vat or meltingpot;upon the surface of the molten metal contained in which are designedto be rested'a plurality of floats, as B, C, and D, preferably'arranged 0n three sides of a'common center and held in such position by the bridgeor yoke E so that the fourth side, which is represented at the bottom of Figure i, is relatively open for convenient access of theladle Q to the measuring member F, which is positioned as desired in the vat though generally centrally of the floats. This measuring` member FV is in the form of a bowl of very slightly'greater in-y ternal size and curvature than the exterior of the ladle Q which is to be used. measuring member is adjustably held at the desired height relatively to the floats and their uniting yoke by means of the upwardly projecting stem or stud Gr, 'which is carried on the bracket H at one Vedge of the measuring member, and slidably passes through the guide sleeve J in the bridge E.' Adjustment of this astoheight may be regulated by some such coin/ementmeans as the 3am screw K.

This inemberor bowl F is pro7 This i vided at its bottom with a hole L of suitable ize to admit the upward flow into the bowl of molten metal contained inthe melting pot A, the degree or extentofits rise thereinto bedetermined'by theraisedlor lowered position of the measuring' member F relatively to the vfloats and consequentlyto the level of the molten metal containediwithin the melting' vat A.

It will be obvious thatif the workman is at all careful and proficient in so scooping out with his ladl-e4 the contents of the measuring `member F, the latterwill be substantially emptied at each ladling operation, and the upward, gravity-manned flow of a refilling quantity of molten metal will at once begin through -the hole Lin the bottom ofthe measuring member, and that this refilling upliow will'contmue until the molten'metal attains the saine level therein as prevails in themelting vat A, ceasing only when the quantity of molten metal left in the pot A is no longer of suiivcient depth to per-mit the iloatmembersB, C, Aand D to function. The

removal of this quantity at the next ladlingr operation will thus insure Ysubstantial uniformity in the quantity of molten metal lthus removed. n

l/Vhile it has been my experience that the arrangement and relative positioning of the float members herein disclosed makes for the greatest convenience and utility of the device, in that it lends buoyant support to the bowl from three sides f while leaving the fourth side open for convenient access of the operators ladle, I do not wish to be understood as restricting myself thereto since the same general principle of, adjustably supporting the apertured bowl at the desired elevation for filling from below with the exact quantity of molten metal desired, could be served with a lesser number of floats va different arrangementy of them, or even by the use of a single float..

`While it Willibe apparent that the illustrated embodiment of my invention herein disclosed is well calculated toadequately fulfill .the objects and advantages primarly stated, it is to be understood that the invention is susceptible to variation, modification and change within the spirit andscope of the subjoined claims. v

Vhat I claim is:

il. Means for effecting uniformity the quantity of molten metal removed from a melting pot by ladling, consisting ot an inieriorly apertured bowl of substantially the `contour of a. ladle, into which molten metal members, a yoke member Alor holding` saidv members in desired position relatively to one another, and an interiorly apertured bowl adapted to be'supported by said iloat members at a suitable eleva-tion for the gravityinduced inilow ot the desired quantity of molten metal.

3. ln combination with a bowl having` an aperture relatively remote from its top edge, buoyant means for supporting said bowl in a fluid mass wherein both are positioned, and means for regulatably varying` the relative elevation ot such bowl with respect to its supporting element.

4. In combination with a plurality ot float members, a correlating yoke whereby said members are held in desired arrangement, and an inferiorly apertured bowl member adjustably supported at the desired elevation relatively to said float members, whereby the inlowing access ot a measured quantity of the fluid, wherein both said float members yand said bowl are positioned, may be automatically effected.

5. In combination with an apertured bowl member, supporting means therejor, comprising buoyant elements adapted to be rested with it on the surface of a fluid mass, and means for regulating the elevation of said bowl member relatively tosaidbuoyant elements, whereby the gravityinduced inflow ot the fluid into said bowl is regulated as to quantity by the degree to which said bowl is held submerged in the iluid.

6. InY combination with a bowl provided with an aperture relatively r-mote from its top edge, means for supporting such bowl at the desired degree of submergence in a fluid mass, comprising a buoyant elementand 2 y reeaaes means for adjustably correlating said bowl therewith at the desired level.

7. The combination, with a. spacedly correlated series olfY float members, of an inferiorly apertured bowl provided with means for its supported connection with said iloat members at the desired relative elevation, for determining the level in said bowl to which the gravity-induced inflow ot the fluid, in which it and its float members are positioned, may rise.

8. The combination, with an apertured bowl member and buoyant means adapted'to be positioned in a fluid mass, ot means for regulatably connecting said members at variant relative levels, whereby the degree to which fluid may enter said bowlthrough its aperture is determined bythe extent of its buoyantly supported submergence therein.

9. The combination, with an apertured bowl, ot buoyant means adapted to support said bowl in affluid mass at such predetermined level as will automatically insure the restriction to a certain maximum of the gravity-induced inilow through said bowls aperture. i

l0. The combination ofa correlated series of buoyant elements and an apertured bowl supported thereby at a predetermined relative level in a fluid-mass, whereby 'said bowl receives the gravity-induced inflow ot such fluid to a predetermined level.

l1. ln combination with an inferiorly apertured icluid-receiving member, float elements whereby said iluid-receiving member is supported against sinking, and means whereby the elevation oi said fluid-receiving member relatively to said float elements may be adjusted. Y

l2. ln combination with a plurality offloat elements, an interiorly aperture-d fluid-receiving` member'positioned intermediately ot said Yfloat elements, and means correlating,`

ysaid fluid-receiving element and said mem bers whereby they are. adjustably held in desired relative position to one another.,

ln testimony whereof I sign this specilication.
